ANTIBLOTTING-RULER.

Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed December 12, 1906. Serial No. 347,499.

T all; uliom it may concern:

Be it known that I, MiLrox \V. ALEXAX- DER, a. citizen of the UnitedStates, residing f at New York, county of New York, and

s v l btate of .\cw lork, have invented certain new and useful Imrovements in Antiblotting-Rulers, of whic i the following is aspecification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter (lo-- scribed andsubsequently claimed.

Reference may be had to the accoiiipanying drawings, and the referencecharacters I marked thereon, which form a part of this specification.Similar characters refer to snnnar parts in the several figures therein.

Figure 1 of the drawings is a view in perspective of the improved ruler,bottom side up, and showing a single sheet of blotting material. Fig. 2is a cross section taken 01;

the broken line x.v in Fig. 1 showing the blotting material in threesheets instead of one sheet. Fig. 3 is a perspective view similar tothat shown in Fig. 1 with the blottiig material detached. Fig. 4 is aview in perspective of one of the end-clips detached.

My invention relates to improvements in a combined ruler and blotter.

The invention consists in providing the under surface of a ruler-bodywith a rabbetgroove adapted to receive one or more sheets of absorbentmaterial, and securing theabsorbent material in such groove by means ofdetachable wire clips inserted in the ends of the ruler-body, andlapping the ends of the absorbent material whereby the form andtll].'-.(ll$l()ll$ of the ruler, when provided with the absorbentmaterial, do not differ.

from the form and dimensions of rulers of the same general characterwhich are not provided with absorbent blotteis.

The object of the invention is to provide i an ordinary ruler with anabsorbent material which can be easily and quickly changed withoutinterfering with any of the functional uses of the ruler as will behereinafter more fully described and pointed out in the claims.-

I have shown an ordinary ruler having one edge beveled and the oppositeedge provided with a projecting ruling surface in combination with threesheets of blotting paper.

. 1, represents the body of the I'll er, and. 2,

a bras strip extending along the beveled l 1 i edge to form a rulingsurface extending lonedge in the common well-known manner.

lThe body of the ruler is provided on its under surface with a rabbet orgroove, 3, extending its entire length. The groove is l of the properdepth to receive the desired,

thickness of blotting material.

The drawings represent the nibbct of the proper depth to receive threesheets, 4, of ordinary )lotting paper, as seen in Fig. 2, l which justfill the rabbet so as to be flush with the unrabbeted portion, 5, of theruler body, a single sheet of blotting material thick enough to fill therabbet being shown in Fig. l. The sheets of blotting paper are de- Itachably secured in the rabbet by means of end clips 66. These clips arepreferably made of wire bent in the form shown in Fig. 4, the shanks, 7,of the cli being inserted in apertures in the ends of the ruler-body,and the heads, 8, being adapted to bear upon the outersurface of theouter sheet of blottin paper, as shown in the drawings, and hold thesheets firmly in place. The ends of the ruler body are preferablyslotted from the cli aperture to the rabbct in order that the yoltes, 9,of the clips may enter such slots the ruler-bod v.' ily become embeddedin the yielding lott-ing sheet so that neither the clips nor the blottersheets will form projections beyond the usual dimensions of the ruler,giving the ruler provided with the blotting sheets the same form anddimensions as ordinary rulers of the same class whichare notprovidedwith antiblott-eis. i If a single sheet of blotting paper isemploved, i it can be easily turned so as to present a clean I surface,after one surface has become satu rated with ink, it only-being necesary to remove the clips, turn the blotter-sheet, and reinsert the clips;and when two or more sheets are employed after the outer sheet has beenused and both sides saturated, it can be placed next to the ruler-bodythus presenting E a fresh sheet upon the outer surface for use am thesheets turned and interchanged until all have been saturated. Such acombination of blotting sheets with a ruler-body and. means for securingthe sheets in position preisents a neat and useful antiblotting ruler lwhich will not interfere with its uses as a ruler for any purposes forwhich a ruler is adapted.

It will be observed that the upper portion of the ruling edge, 10,overhangs or projects beyond the lower portion, 12, of the same i andnot project beyond the end surfaces ofl The heads of the clipsreaditudinally 01' the ruler-body. The strips of I blotting paper arepreferably of a width to complete y fill the rabbet-groove and extendto, or a little beyond, the edge, 12, so that 5 when a penis used inconnection with the ruling surface of the edge, 10, the ink cannot byany possibility through contact with the subtending edge, 12, de )osit ablot of ink upon the paper being ruled, an Y ink which might be de)osite d upon the lower edge, 12, being absor ed by the sheet ofblotting paper. lVhile one of the longitudinal edges of the ruler hasbeen shown beveled, it is obvious that this edge may be of any knownform or material.

\Vhat I claim as new and desire to secure by Letters Patent is:

1. The combination with a ruler-body having a rabbet-groove on its lowersurface; of absorbent material filling such groove, and detaehablysecured therein whereby the lower surface of the absorbent material isin the same plane with the lower surface of the ruler-body adjacent tosuch rabbet-groove. 5 2. The combination with a ruler-body having on oneof its longitudinal edges an overhanging ruling surface, and arabbetgroove on its lower surface extending longitudinally throughoutthe length of the ru er and transveisely from the edge s'ubtending theruling surface )artway only to the 0 150- site edge of the ruler-body;of an absorbent material filling the rabbet-groove and means I fordetachably securing the absorbent material within such groove.

3. The combination with a ruler-body having a rabbet-groove on its lowersurface extending from end to end of the ruler-body of one or moresheets 01'- absorbent materia adapted to fill such rabbet-groove; andend- 40 cli )s severally provided with shanks detachably inserted in theends of the ruler-body and heads for lapping the ends of the absorbentmaterial.

4. The combination with a ruler-body provided on its under-surface witha rabbetgroove extending from end to end of the ruler-body, each end ofthe ruler-body being provided with a clip-aperture, and a slot eX-.tending from the clip-aperture to the rabbet- 5o groove; of one or moresheets of absorbent material adapted to fill such rabbet-groove; andend-clips severally comprising shanks and yokes adapted to be detachablyinserted in the clip-apertures and slots respectivcly in the ends of theruler-body and heads ada )ted to respectively lap the ends of theblotting material.

In testimony whereof, I have hereunto set my hand this 28th day ofNovember, 1906.
